O.K. I was setting up an item for a photograph and I got the LiveMail “note” that a note had arrived from NASA. Their announcements and images are always interesting and I was in need of a break. What follows is their image of the day:
This is not a “real” photograph. To better understand Saturn's rings some of the scientists assigned colors to certain sizes of the chunks of rocks and ice in the rings. That is what produced this image.
Although it is false color, it is wonderfully cool.
We are always doing this to alter images. Most of the tools, plug-ins and adjustments simply play on the characteristics of the pixels we have identified.
All of the Hubble, Chandra and Kepler images are binary – and the colors we see are inferred.
One of these days we will have a ring around our little planet. Space debris, assorted junkers and clunkers from our early space explorations, maybe a few busted asteroid or two. Will the Moonerinians think it is pretty? © Tim www.timjohnsonphoto.com
